CAR-AXLE BOX.

Specification of Letters Patent.

Patented Oct. 22', 1907.

Application filed November 13,1906. Serial No. 343,256.

To all whom it may con/(mm:

Be it known, that I, HARRY C. IVICCARTY, a citizen of the United States, residing in Williamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Car-Axle Boxes, of which the following is a specification.

This invention relates to the lids of journal boxes, and especially to the lids of car axle boxes. The object of the invention is to provide an improved form of lid that will prevent the escape of the lubricating oil in the journal box through the front opening that is nor mally closed by the lid.

In the accompanying drawings showing journal boxes with my improved lid applied thereto, Figure 1 shows in vertical section a journal box embodying one embodiment of my invention. Fig. 2 shows another form of journal box with the same form of lid in the open position. Fig. 3 is a front view of the lid sepa rate; and Fig. 4 is a rear view or inner side view of the same. Fig. 5 is an enlarged view showing the lid and its adjacent portion of the journal box, and Fig. 6 shows in section a form of journal box and lid at present in use.

In one construction of car axle journal box and lid, in very large use, a rib is provided on the inner portion of the lower edge of the journal box opening, such as the rib 9 shown in Fig. 6, in which a space 10 or channel is formed between the outer face of the rib 9 and the inner face of the lid 11. In this space the oil will be thrown by the centrifugal action of the journal and flows down between the lid and box. As soon as the lid is lifted to inspect the box or to supply a fresh quantity of lubricant, the oil remaining in this recess flows down the outer face of the rib onto the ground. And this construction is further objectionable in that when the lid is closed, the accumulation of oil remaining on the surfaces engaged by the lid will be struck by the lid and -ause splashing ol' the oil on the attenda'nt. To overcome such liability to waste of the oil .and the objections of this design I provide the lid with a projection or rib entirely around the four sides of the opening in the front of the.hox see Figs. 1 and 2. The lid 12 is shown as provided with a rib 13 whose bottom face 14 is curved on an arc whose center lies in the axis of the pivot lb of the lid. The front of the journal box has the usual opening 16 whose lower edge i7 is inclined downwardly to engage a corresponding inclined face 18 on the lid, extending from the curved portion 1 1 to its outer face. The upper edge of the bottom face 17 of the opening will remain in the same relative position to the curved face 14 as the lid swings open, and should any oil remain adhering to this curved face, it will be swept or scraped off of this edge by the face 17. The oil that is thrown from the axle striking the center part of the lid on its inner face will flow down the curved surface and over the rib 14, and thence drop into the box. But as stated, the oil that might adhere to the curved face 14, when the box is open will be practically scraped off by the edge 17 of the opening in the box. All ear or handle portion 19 is provided in the usual manner to facilitate the opening and closing of the box lid.

A plate spring 20 is shown in the usual way secured to the inner face of the lid 11 engaging the box frame at 21 at the upper edge of the opening for the lid. This spring will serve to retain the lid in the closed position in which it is shown in Fig. l. to retain the lid in the open position as shown, but will tend to throw the box lid back to the position indicated in broken lines in Fig. 6. When in this position, the lid requires practically two movements to close it, a forward horizontal movement and then a downward or vertical movement.

ward movement will serve to easily and quickly bring the lid to its closed position.

Having described my invention I claim:

1. A car wheel axle box having an opening in one end, and a lid pivotally mounted to swing to and from the opening in the box, the lid having its lower edge beveled or inclined from its outer face inwardly and arranged to engage the bottom edge of the frame by said inclined edge when the lid is closed, the lid also having a rib projecting in \vardly and downwardly from the said inclined lower face of the lid, the lower face of the rib makingan angle with the adjacent inner face of the frame member and being en tirely free from contact therewith.

2. A car wheel axle box having an opening in one end, and a lid pivotally mounted to swing to and from such open- 111;: in the box, the bottom edge of the opening in the box frame being inclined to the plane of the lid in the'closed position, the lid having its lowenedge beveled inward and upward from its outer face to engage said inclined bottom edge of the opening, the lid having a rib at its lower portion projecting inwardly and downwardly and having its lower face free from the inner adjacent face of the box and making an angle therewith.
